A dog digging "obsessively" in its backyard tipped off its owner to a number of unusual items, including doll fragments, a ceramic pot and what appeared to be human and animal skeletal remains, police said Thursday in Yuba City, Calif.

HURT. NO WORD ON WHAT STARTED THAT FIRE. A DOG DIGGING IN A BACKYARD LEADS ITS OWNERS TO FIND AN UNUSUAL FIND. A HUMAN SKULL. IT WAS A NORMAL WEEKNIGHT WHEN SKY, A HUSKY BECAME FIXATED ON A SPOT IN THE BACKYARD. SHE NEVER DIGS IN THE YARD OR ANYTHING, BUT SHE BECAME FIXATED. THE HEAD -- IT LOOKS LIKE THE HEAD OF A DOLL. IT LOOKS VERY CREEPY. BURIED OUTSIDE OF THE POT WERE MACHETES. THEY WOULD LATER LEARN THAT OTHER ITEMS WERE HUMAN SKELETAL REMAINS. THEN A HUMAN JOB BONE AND A SKULL THAT INVESTIGATORS WERE DETERMINED WAS OF THE HUMANKIND. YOU MUST CITY POLICE -- YUBA CITY POLICE SAY THESE ITEMS ARE ARTIFACTS FROM AN AFRO-CARIBBEAN RELIGIOUS TRADITION. THERE WERE SOME COINS IN THERE AND WE WERE UNABLE TO IDENTIFY ONE CALLING. THERE IS A PENNY FROM 1995. HOPEFULLY WE WILL FIND A STORY
